Yesterday I ran the Surface Diagnostic Toolkit, (I have a Surface Laptop 2, running Windows 10 pro 1903) because of some other issue.
Now starting the VPN from the system tray network icon does work!
My build is now: 18362.592
I also see in the windows update history that 2 days ago 2 other updates have been installed:
- https://support.microsoft.com/en-us/help/4532938/kb4532938-cumulative-update-for-net-framework
- https://support.microsoft.com/en-us/help/4528760/windows-10-update-kb4528760
That may also have fixed it.
Hope this helps you all.
